AUTOMATIC MACHINE FOR STRIPPING LND RE-COVERING WIRE.

Specification of Letters Patent.

Patented Aug. 1, 1911.

Application led February 25, 1911. Serial No. 610,709.

T o all whom it may concern:

Be it known that I, JAMES H. E. BRAN soN, a citizen of the UnitedStates, residing at the city of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Automatic Machines for Stripping and Re-CoveringVire, of which the following is a specification.

My invention relates to an automatic machine for stripping or removingdefective insulation from wire employed in dynamos, electric lighting,etc., and preparing the wire then to receive a new tape or fillet ofinsulating material for restoring the saine to practical condition foruse; and in such connection it relates to the constructive arrangementof such a machine, for the said defined purpose.

The nature, scope and characteristic features of my present inventionwill be more fully understood from the following description taken inconnection with the accompanying drawings forming part hereof, in which-Figure l, is a top or plan view of a machine for stripping insulatedwire and recovering the same, embodying main features of my invention.Fig. 2, is a side elevational view thereof; and Fig. 3, is a verticalsectional view, in broken section, of the speed changing disk-wheel ofthe machine.

Referring to the drawings, c is a framing carrying in one portion aripping device b, consisting of a series of staggered threaded boltsextending fro-m a plate b1, and detachably connected with the framing a.This ripping device is arranged so that in the passage of the insulatingcovered wire 0, in a circuitous course over and under the staggeredthreaded bolts of the said plate, the defective insulation of the wireis removed by being rip-ped or torn off, from the wire, by contactingwith the series of threaded bolts, in a manner, as clearly shown in Fig.2.

CZ, is a funnel-shaped device projecting from the framing a, and throughwhich the wire c, passes to thoroughly clean or scrape proper adjustableoperative posit-ion on tlie"v\ journal g1, by means of a nut g2. Throughthe journal g1, the wire c, passes after being conducted under aguide-wheel (Z1, of the framing a, and passing over a feed pulley (Z2,mounted on a shaft cl3, having bearings in the framing a, and carryingat the free end a friction disk or wheel 7L. This wheel h, is keyed tothe shaft cl3, and provided with an exterior threaded hollow stem 71.1,which engages an internally threaded sleeve 71.2, as clearly shown inFig. 3, whereby through turning the sleeve on the stem h1, of the diskor wheel 7i, the speed of rotation of the disk-wheels g and 7i., can bereadily increased or decreased ad Zzz'tum, and correspondingly thereby,the laying of the fillet, strip or tape e, on the wire c, from the reel,carried by and revolved with disk or wheel g, as clearly shown in Fig.1.

In the operation of the machine the series steps are automa-tic, andcontinuous as to the stripping of the insulated covering from the wireheld under tension, as well as the thorough cleaning of the same of allex' wire, consisting of a series of staggered bolts extending from aplate, said bolts having threads engaging the insulation to rip mysignature in the presence of two subthe same from the Wire combined withsorbing Witnesses. means to scrape or clean the Wire and means T toapply a fillet, strip or tape to the Wire, JAMES H' E' BRANSOBsubstantially as and for the purposes de- Witnesses: scribed.
